Deep Sky Objects (DSOs) are celestial bodies located outside our solar system, primarily found in the Milky Way galaxy and beyond. They include a variety of astronomical phenomena such as galaxies, nebulae, and star clusters. These objects are often studied using telescopes, as they are too distant to be seen with the naked eye. DSOs are categorized into two main types: extragalactic objects, which are located outside our galaxy, and galactic objects, which are found within it. Observing these objects helps astronomers understand the universe's structure, formation, and evolution over time.
